What are the routine maintenance items for electric vehicles?
3 Answers
Electric vehicles routine maintenance items include: 1. Inspect paint damage, light functions, wiper blade aging degree, tire wear and pressure; 2. Replace the cabin air filter; 3. Check and replenish coolant, brake fluid, and windshield washer fluid; 4. Inspect the power system's connector interfaces and wiring insulation protection. An electric vehicle consists of a power battery, chassis, body, and electrical components. Its working principle is: The driver controls the electronic accelerator pedal, sending analog electronic signals to the controller or processor, which then processes these signals to regulate the motor's output power, rotation speed, and direction of rotation.
I just had the second maintenance for my electric car recently, and found it's quite different from traditional fuel cars. EV maintenance mainly focuses on the battery system - the shop uses professional equipment to check battery health status and voltage balance of each battery module. Secondly, they must upgrade the vehicle control system software, which is super important as manufacturers frequently optimize energy recovery logic. For mechanical parts, brake system inspection is particularly crucial since we use regenerative braking more often, making brake discs prone to rust. Then the coolant must be checked as it maintains battery pack temperature stability. Tires require special attention too - EVs' quick acceleration wears tires faster, and the mechanic said my treads are wearing quicker than expected. Oh, and it's best to replace cabin filters every season since EVs use AC more frequently, especially during winter when heating consumes more power. The maintenance checklist has fewer items than fuel cars but is highly targeted.
As a commuter who has driven an electric car for three years, what annoys me most is being tricked into unnecessary maintenance. There are actually just five essential items: Battery inspection is mandatory, checking capacity degradation and thermal management. Motor bearings need lubrication—though simpler than an engine, they still require care. Brake system maintenance is unique; mechanics must disassemble and clean the calipers, as regenerative braking reduces brake pad wear, increasing the risk of sticking. AC system disinfection is recommended twice a year (spring and autumn)—since heating and cooling rely on electricity, damp pipes can breed bacteria. Lastly, inspect the undercarriage for battery casing damage after impacts. Other tasks like wiper blades and washer fluid can easily be DIY. Remember: don’t fall for throttle body cleaning—our EVs don’t even have one!
